18. Ill-Bred

Complete story — includes the ending

Veterinarian Molly Sims ( Tari Signor ) is killed in the stalls of horse racing stables owned by James ( Mark Pinter ) and Marguerite ( Bronwen Booth ) Townsend. Detectives Goren and Eames discover married stable employees Dale ( Fred Weller ) and Paige ( Dana Eskelson ) Mullen appear to be smuggling heroin in the horse's uteruses while attending domestic and international thoroughbred competitions. Further investigation uncovers that Dale is having an affair with Marguerite Townsend and that his wife Paige planned to exploit both of them by increasing the possibility of Marguerite having a child with Dale. Paige planned blackmail her employer and set up her own dream horse farm for which she has already paid a deposit without Dale's knowledge. When Goren and Eames find that Marguerite is now pregnant, they deduce that Paige was motivated to kill Sims to prevent her from exposing their drug-smuggling scheme before Marguerite gave birth.
